Answer:
By changing pyruvate into lactic acid with this transfer of electrons.
Explanation:
Transfer of electrons helps the lactic acid fermentation process repeat itself because the pyruvate molecule takes electron from NADH which is reduced to lactic acid so indirectly with the transfer of electrons helps the lactic acid fermentation process to repeat itself. If these electrons are not transferred from NADH to pyruvate molecules so the lactic acid is not formed.
